Is it possible to import OrCAD libary file *.OLB into Solidworks Electrical?
As far as I'm aware of no, not directly.
Probably best to looking into if using .IDF or .DWG as an in between file format helps you out.
Maybe into SW PCB, but not Electrical that I'm aware of. You can always import .DWG's into electrical though. They won't be intelligent with parts/circuits recognized but if you just need the orcad files for reference then that would be fine.
